Fig. 5 is a fragmentary sectional view showing a flush sash guideembodies an outer side wall 16-a and a bottom wall 18a.

In this construction the T-shaped sash guide spring element is indicatedgenerally by the numeral 23-a. It does not have its upright portion26-11 bent into angular shape as shown in Fig. 3. Such upright portion26-a extends through apertures in the sash guide 36 as shown in Fig. andis secured thereto by a screw 42 as shown in such figure.

The head portion 28-a of this T-shaped element 23 is provided withsuitable tenite wear buttons 44 wrapped therearound and seated withinnotches formed therein, all as shown in Figs. 6, 7, and 8. The T-shapedspring element is positioned in the same manner and functions in thesame manner as the corresponding element described in connection withFigs. 1-4.

It will be noted that these two T-shaped spring elements 23 and 23-a aredisposed in complementary positions upon the opposite sash guide stripssubstantially midway between their ends and in a position to engage thelower sash adjacent its lower end. The upper end of the lower sash isshown as overlying the bottom end of the upper sash and the T-shapedelements hold the two sash outwardly against the outer side wall 16 ofthe sash guide. This is true whether the T-shaped element is of thecharacter shown in Fig. 3 or as illustrated in Fig. 5. It is readilypossible to insert and remove the lower sash L from the framework of theassembly. Such may be done from the inside of the building.

What I claim is:

1. In a sash guide assembly provided with complementary opposed jambportions for two sliding sash and wherein each jamb portion comprises asash guide having a bottom wall and an outer side wall disposedgenerally perpendicularly with respect to each other, a

pair of generally T-shaped spring elements secured to complementaryopposed intermediate portions of said sash guides, each spring elementhaving its upright part secured to the sash guide with the head of the Tshape spaced above the bottom wall of the guide substantially parallelto the outer side wall and in line with that edge of the bottom wallremote from the outer side wall, said head being generally arcuate inshape and with its opposite ends projecting toward and tensioned towardthe outer side wall of the guide and each provided with a plastic wearbutton secured thereto on the concave side and projecting therebeyondtoward the outer side wall of the guide to form sliding engagement witha sliding sash mounted within said guide.

2.
